These movable rods l2 are each provided 55 which the following is a speciiication, referwith a reduced portion 13, located in'and ence being had therein to the accompanying adapted to travel up and down in holes eut drawings. through cross-piece 7 as the knife is carried lo This invention relates to improvements in to move over the molds.

The object of the invention is to provide At both ends of the knife on the pins 1l I new and improved means for cutting and reprovide a casting comprising a collar 1G,

moving the surplus clay in the molds after journal 17, and a circular slide 18. Slide 1S 65 the brick-forms have been passed through is provided with a projection 19, which is the brick-inachlne-that is to say, after the arranged to enter slots 20, formed in the rails clay is pressed within the molds in the usual 2l, which latter are suitably attached to the zo manner and the molds containing the clay posts 1.A Extending downwardly from crosshave been released from said pressure the piece 7 and extending tothe rear of vthe knife 7o clay expands a certain amount and it is n ecare two pushing-rods or kickers 22.

Raising the coupling coupling member 6. Bent rod 5 extends member 6 by means of the lever 4 causes the downwardly through a cross-piece 7 and is knife tobeturned overinto theposition shown by Fig. 2. This is accomplished by reason of the projection 19, on the circular slide 18, coming in contact with the end of the slot 20. This turns the pins 11, on which the knife is mounted, thereby bringing the knife into the desired operative position. Continuing the pull on the coupling member 6 causes the knife to travel over the mold and the mold to be pushed forward to the position shown by dotted lines in Fig. 2. When the slide 1S, with its projection 19, reaches the forward end of the rails 21, said projection 19 falls into slot 20, thus causing the knife to turn over and to assume a position for removing durf ing the return travel of the knife the surplus clay not removed during the forward travel of the same over the mold.

What I claim is- 1. In an attachment for brick-machines, the combination with a table, a movable knife arranged to travel over molds located on the table, a cross-piece, means for supporting the crosspiece, oscillating and vertically-movable rods for supporting the knife and means for actuating the knife, substantially as set forth.

2. In an attachment for brick-machines, the combination with a table, a movable knife arranged to travel over molds located on the table, a cross-piece, means for supporting the cross-piece, oscillating and vertically-movable rods for supporting the knife, a pusher attached tothe cross-piece, and means for actuating the knife, substantially as set forth. 3. In an attachment forbrick-machines, the

combination with a table, a movable knife arrange-d to travel over molds located on the table, a cross-piece, means for supporting the cross-piece, oscillating and vertically-movable rods for supporting the knife, a slotted track, means carried with the knife arranged to travel on the track and to enter the slots in the track whereby the knife is brought into operative positions, and means for actuating the knife, substantially as set forth.

4. An attachment for brick-machines, comprising a frame, a table, a movable knife arranged to travel over molds located on the table, a slotted track, means carried With the knife arranged to travel on the track and to enter the slots in the track whereby the knife is caused to assume an operative position about midway of the molds on its travel in one direction over the molds and caused to be turned and to assume an operative position about midway of the molds upon` the return movement of the knife, and means for actuating the knife, substantially as set forth.

In testimony whereof I affix'my signature in presence of two witnesses.
